Question 1

Good DS Habits

Answer 1

DS Process

• Booby traps
• T chart (reference notebook)
• Always use the framework for DS - commit to it
• Can’t assume positive or integer
• Rephrasing: 3 forms = Algebra, Logic, Testing Cases
• More complicated statement = you SHOULD guess sufficient
• There’s value and Y/N

Good DS Habits

• Dashes for numbers
• Boxes for digits
• Yes-No is asking for “can I always get a yes or can I always get a no”
• Don’t fall into the C-trap
• If the statements look similar, it’s probably 1 or 2 but not both
